HARD DISK CAMERAS

Surveillance Hard Drive. It’s a solid piece of hardware, but it is specifically designed for a very particular job.
​Here is the breakdown of what you have and how it differs from a standard computer drive:
​Key Specifications
​Capacity: 500GB
​Form Factor: 3.5-inch (standard desktop size)
​Interface: SATA 6 Gb/s
​Specialization: Surveillance (optimized for 24/7 recording)
​Why "Purple"?
​Western Digital uses colors to categorize their drives. While a WD Blue is for everyday PC use and WD Black is for high-performance gaming, WD Purple is built for NVR (Network Video Recorders) and DVR systems
